of injury, or physical damage, if not carried out properly.
Symbol:
Prohibited Mandatory
Precautions During Flight
Do not fly or turn "On" simultaneously on the same frequency.
Interference will cause a crash.
Use of the same frequency will cause interference even if the
modulation method (AM, FM, PCM) is different.
Do not fly on rainy or windy days, or at night.
Water will penetrate into the transmitter (Tx) and cause faulty
operation, or loss of control, and cause a crash.
-4-

Do not fly in the following places:
-Near other R/C flying fields (within about 2.5miles [3km]
-Near people on the ground, or objects in the air
-Near homes, schools, hospitals, or other places where there are a lot of people
-Near high tension lines, high structures, or communication facilities
Radiowave interference and obstructions may cause a crash. A crash caused by trouble in the R/C set, or the model
itself, may cause death or property damage.
Do not fly when you are tired, sick, or intoxicated.
Fatigue, illness, or intoxication will cause a loss of concentration or normal judgment and result in operation errors and a
crash.
Extend the antenna to its full length.
If the antenna is shortened, the effective range of the radio signal
will be shorter.
Always test the R/C set before use.
Any abnormality in the R/C set, or model, may cause a crash.
Before starting the engine, check that the direction of operation of
each servo matches the operation of its control stick. If a servo does
not move in the proper direction, or operation is abnormal, do not
fly the plane.
Check that the transmitter (Tx) antenna is not loose.
If the transmitter antenna comes off during use, control will be lost
and the model will crash.
When placing the transmitter (Tx) on the ground during flight preparations, be sure that the wind cannot
knock it over.
If it is knocked over, the throttle stick may be pushed to full throttle, the engine will speed up and create a very
dangerous situation.
Do not touch the engine, motor, or FET amp (speed control) during and immediately after use.
They are hot and will cause a burn.
-5-

Turning on the power switch:
Set the transmitter (Tx) throttle stick to idle.
1. Turn "On" the transmitter (Tx) power switch,
2. Then turn "On" the receiver (Rx) power switch.
Turning off the power switch:
Stop the engine,
1. Turn "Off" the receiver (Rx) power switch,
2. Then turn "Off" the transmitter (Tx) power switch.
If the Tx power switch is turned off first, the engine may go to full throttle unexpectedly and cause an injury.
Idle: The stick direction in which the engine or motor runs at the slowest speed. (usually the down position)
When adjusting the R/C set, always stop the engine.
If the engine suddenly goes to full throttle, it may cause an injury.
Nicd Battery Charging Precautions
Always charge the nicd batteries before each flight.
If the battery goes dead during flight, the plane may crash or fly away.
Charge the R/C nicd battery with the standard charger, or fast field charger. (sold separately)
Overcharging may cause burns, fire, injury, blindness, etc. due to overheating, breakage, electrolyte leakage, etc.
-6-

Do not short the nicd battery connector terminals.
Shorting the terminals will cause sparking and overheating and result in burns or fire.
Do not drop or apply strong shock to nicd battery.
The battery may short out and cause overheating or breakage
and electrolyte leakage and result in burns or damage from
chemical contents.
Storage and Disposal Precautions
Do not leave the R/C set, battery, model airplane, etc. within the reach of small children.
Touching and operating the R/C set, or licking the battery, may cause injury or damage due to chemical content.
Do not throw the nicd battery into a fire or heat the nicd battery. Also, do not disassemble or rebuild the nicd
battery.
Breakage, overheating, and electrolyte leakage may cause injury, burns, or blindness.
Nicd Battery Electrolyte
The electrolyte in a nicd battery is a strong alkali and can cause blindness if it gets in the eyes. If you get the electrolyte
in your eyes, immediately wash your eyes with water and see a doctor. If you get the electrolyte on your skin or clothes,
it may cause a burn. Immediately wash it off with water.
-7-

Do not store the R/C set in the following places:
-Where it is very hot (75°F [40C] or more) or very cold (18°F [-10C] or less).
-Where the set will be exposed to direct sunlight.
-Where the humidity is high.
-Where there is strong vibration.
-Where it is dusty.
-Where there is steam and heat.
Storing the R/C set in the places listed above may cause distortion, corrosion and product failure.
If the R/C set will not be used for a long time, remove the nicd batteries from the transmitter and the model and
store them in a dry place.
If the batteries are left in the transmitter and model, the battery electrolyte may leak out and damage the system, degrade
the performance and shorten the life of the transmitter and model.
Nicd Battery Recycling (for USA only)
Used nicd batteries are an important resource. Stick tape over the terminals and take the used batteries to a nicd battery
recycling center.
The RBRC Battery Recycling Seal on the nickel-cadmium (Ni-Cd) battery that should be used
in our product, indicates Hobbico is voluntarily participating in an industry program to collect
and recycle these batteries at the end of their useful life, when taken out of service in the United
States or Canada. The RBRC program provides a convenient alternative to placing used Ni-Cd
batteries into the trash or the municipal waste system, which is illegal in some areas. Please
call 1-800-822-8837 for information on Ni-Cd battery recycling in your area. Hobbico's
involvement in this program is part of our commitment to preserving our environment and
conserving our natural resources.
Other Precautions
Do not get fuel, oil, etc. on plastic parts.
The plastic may melt, discolor, become brittle and fail to function.
Always use Genuine Futaba transmitters, receivers, servos, ESCs, nicd batteries, and other optional parts.
Futaba is not responsible for damage, etc. caused by the use of parts
other than Genuine Futaba parts.

Transmitter Operation and Movement of Each Servo
Before making any adjustments, learn the operation of the transmitter and the movement of each servo. (In the following
descriptions, the transmitter is assumed to be in the operating state.)
Aileron Operation
When the aileron stick is moved to the right, the right aileron is raised and the left aileron is lowered, relative to the
direction of flight, and the plane turns to the right. When the aileron stick is moved to the left, the ailerons move in the
opposite direction. To level the plane, the aileron stick must be moved in the opposite direction. When the aileron stick is
moved and held, the plane will roll.
Elevator Operation
When the elevator stick is pulled back, the tail elevator is raised and the tail of the plane is forced down, the air flow
applied to the wings is changed, the lifting force is increased, and the plane climbs (UP operation). When the elevator
stick is pushed forward, the elevator is lowered, the tail of the plane is forced up, the air flow applied to the wings is
changed, the lifting force is decreased, and the plane dives (DOWN operation).
Throttle Operation
When the throttle stick is pulled back (low throttle), the engine throttle lever arm moves to the SLOW (low speed) side.
When the throttle stick is pushed forward (full throttle), the throttle lever arm moves to the HIGH (high speed) side.
Rudder Operation
When the rudder stick is moved to the right, the rudder moves to the right and the nose moves to the right, relative to the
direction of flight. When the rudder stick is moved to the left, the rudder moves to the left and the nose moves to the left.

INSTALLATION AND ADJUSTMENT
This section describes the installation and adjustment of the receiver, servos, etc. to the plane.
Connections
Connection examples are shown below.
Connection Example
•Four servos are supplied as standard.
-15-

-16-
(Connector Connection)
Insert the receiver, servo, and battery connectors fully and firmly.
If vibration, etc. causes a connector to work loose during flight, the plane may crash.
(Receiver Vibration proofing / Waterproofing)
Vibration proof the receiver and battery by wrapping them in sponge rubber or
some such material. If the receiver may get wet, waterproof them separately by
placing them in plastic bags or balloons.
If the receiver is subjected to strong vibration and shock, or gets wet, it may operate
erroneously and cause a crash.
(Receiver Antenna)
Do not cut or bundle the receiver
antenna. Also, do not bundle the antenna
together with the servo lead wires.
Cutting or bundling the receiver antenna will
lower the receiver sensitivity and shorten the
flight range and cause a crash.
Antenna installation: For aircraft, attach the
antenna to the top of the tail.
(Servo Throw)
Operate each servo over its full stroke and adjust the linkages so that the pushrod
does not bind or is not too loose.
Unreasonable force applied to the servo horn will adversely affect the servo and drain
the battery quickly.
Power Switch Installation
When installing a receiver power switch to the fuselage, cut a rectangular hole
somewhat larger than the full stroke of the switch knob and install the switch so it moves
smoothly from ON to OFF.
Always install the switch so it will not come into direct contact with engine oil, dust, etc.
Generally, install the switch to the fuselage at the side opposite the muffler exhaust.
(Servo Installation)
Install the servos to the servo mount, etc. using a rubber
grommet. Also install the servos so that the servo case does
not directly touch the servo mount or other parts of the
fuselage.
(Servo Horn Screw)
Use the horn screw supplied with the servo.
If a long screw is used, the interior of the servo may be damaged.

-17-
Adjustments
The operating direction, neutral position, and steering angle of each servo are adjustable.
The basic linkage and adjustments, control layout, and servo, Rx and Nicad
installation should conform to the fuselage design drawings and kit instruction
manual. Be sure that the center of gravity is at the prescribed position.
Adjustment Procedure
Before making any adjustments, set all the SERVO REVERSING switches on the front
of the transmitter to the lower(NOR) position and set both Dual Rate
trimmers(AIL./ELV.) to the maximum ("10") point. (Set the switches and the trimmers
with a small screwdriver, etc.)
Turn on the transmitter and receiver power switches and make the following
adjustments:
1. Check the direction of operation of each servo.
If a servo operates in the wrong direction, switch its SERVO
REVERSING switch. (The direction of operation can be changed
without changing the linkage.) Pay special attention to the direction of the aileron. (See
page 14 for a transmitter operation instruction.)
2. Check the aileron, elevator, and rudder
neutral adjustment and left-right (up-down)
throw.
Check that when the Tx trim levers are in the
center, the linkage connection point is
perpendicular to the servo. In this position the
control surfaces (aileron, elevator, rudder, etc.)
must be neutral. If the neutral position of the
control surface has changed, reset it by
adjusting the length of the rod with the clevis.
When the throw is unsuitable (different from the deflection angle specified by the kit
instruction manual), adjust it by either changing the servo horn, the position of the
linkage on the servo horn or the linkage position on the control surface horn.
3. Check the engine throttle (speed adjustment) linkage.
Change the servo horn installation position and hole position so that the throttle is
opened fully when the throttle stick is set to HIGH (forward) and is closed fully when
the throttle stick and throttle trim are set for maximum slow (backward position and
lower position, respectively).
4. After all the linkages have been connected, recheck the operating direction,
throw, etc.
Before flight, adjust the aircraft in accordance with the kit and engine instruction
manuals.
5. Fly the plane and trim each control for straight and level flight.

-18-
USING OTHER FUNCTIONS
Non-slip Adjustable Lever Head
The length of the stick head can be adjusted.
1. Unlock two heads A and B by turning them in the
arrow directions.
2. Adjust the stick to the most comfortable length and
lock the heads by turning them in the opposite direction
of the arrows.
Aileron/Elevator Dual Rate (D/R) Function
The maximum travel of the aileron and elevator servos can be altered by operating the
dual rate switch. For instance, when the switch is in the lower position, the deflection
angle is the normal deflection angle. The normal deflection angle, at the low switch
position, can be adjusted by the dual rate trimmers (AIL/ELV). The rate can be adjusted
from 50% (position 0) to 100% (position 10) of the maximum deflection angle. When
the switch is set to the upper position, spins, snap rolls, and other aerobatics that require
a maximum deflection angle can be performed.
1. Turn on the transmitter and receiver power.
2. Switch the dual rate switch (D/R) to the lower position.
3. Set the stick to the maximum travel in either direction.
4. Using the trimmer, adjust the servo horn to the desired angle.
Adjust each channel (AIL/ELV) by repeating steps 1 through 4.
*When not using the dual rate function, set the AIL and ELV trimmers to 100%
(fully clockwise).

-19-
Trainer Function
The trainer function is a very effective way for training students. To use it, the special
trainer cord TC-FM (FUTM4410 USA only - sold separately) is necessary.
The special trainer cord can be connected to SKYSPORT4, SKYSPORT6, 7U series, 8U
series, and PCM1024Z series transmitters.
Connection
Connect the student and instructor
transmitters with the trainer cord.
Never turn on the student transmitter power switch.
Turning on the power switch will cause interference and a crash.
Set the student and instructor transmitter functions and trims to the same settings.
For example, if the direction of operation is reversed, control will be lost and the plane
will crash.
Both transmitters must have the modulation type that is FM type.
If the modulation type is different, control is impossible.
Stick Lever Spring Tension Adjustment
The operating feel of the aileron, elevator, and rudder sticks can be individually adjusted
by adjusting the stick spring tension.
1. Remove the four transmitter rear case screws
and carefully remove the rear case.
2. Adjust the spring tension by turning the screw
of the channel you want to adjust (clockwise to
stiffen counter-clockwise to soften).
3. Close the rear case and tighten the four
screws.
Operating Instructions
Instructor side: Turn "on" the power switch and extend the antenna to its full length.
When the trainer switch is not activated, the instructor has control. When the trainer
switch is activated, control is transferred to the student. Release the switch to retain
control.
Student side: Never turn on the power switch.
